Bifold Shower Seal - 7mm T-Head, 12mm Tall, Seals 7-12mm Gaps

What this seal is

A clear soft-PVC channel seal for bifold shower doors and bath screens, sized for larger gaps. The 7mm T-head slides into the channel in your door frame — no adhesive needed — and the 12mm-tall body closes gaps of 7mm to 12mm, keeping water inside the enclosure as the door folds and unfolds.

As well as the bottom of a bifold door, it also works vertically on glass uprights to seal between the glass and a tiled wall.

How to check it fits your door

Measure the slot in your frame — this T-head needs roughly 7mm — and the gap you need to close, which should sit between 7mm and 12mm. Compare your old seal's end profile against the cutaway in the first photo; if in doubt, the soft body compresses, so a slightly snug fit seals better than a loose one.

Specification

Why fit this seal

Stops leaks from bifold doors. A hardened or split channel seal is the usual reason water escapes from a folding door onto the bathroom floor. A fresh seal protects flooring, skirting and plaster from long-term water damage.

No adhesive, no mess. The T-head simply slides along the existing channel in the frame — no glue required, and the old seal slides out just as easily. A bead of silicone is optional if you want it fixed permanently.

Made for bigger gaps. With a 12mm-tall body sealing 7–12mm gaps, this profile closes the larger clearances that standard bifold seals cannot reach — and the clear PVC is barely visible once fitted.

Easy replacement. The soft PVC trims with household scissors and fits in minutes.

Fitting in three steps

1. Measure. Measure your frame slot (around 7mm for this T-head), the gap you need to close, and the length of channel to fill.

2. Choose. Pick the 1000mm or 2000mm length at or above your measurement, or add custom cutting and it arrives ready to fit.

3. Fit. Remove the old seal and wipe the channel clean. Trim the new length to size if needed, then slide the T-head along the channel until the seal sits flush end to end.
